Interference pattern can be observed due to superposition of the following waves: A. y = a sin ωt

Question

Interference pattern can be observed due to superposition of the following waves:

A. \(y = a \sin \omega t\)

B. \(y = a \sin2 \omega t\)

C. \(y = a \sin(\omega t - \phi)\)

D. \(y = a\sin3 \omega t\)

Choose the correct answer from the options given below.

(1) B and C

(2) B and D

(3) A and C

(4) A and B

Answer 1

Correct option is : (3) A and C

For interference pattern to be observed the sources must be coherent.

Hence the superposition of waves \(y = a\sin(\omega t) \) & \(y = a \sin = a \sin(\omega t - \phi)\) would result in interference.
